In a disk faucet and other single-handle models (above), the diverter valve is typically placed horizontally in the faucet body. On a two-handle faucet, the valve is likely situated vertically in the center of the spout.

Step 1

Pull the sprayer out and use pliers to dismantle the spout, keeping track of all its parts. Clean them with a toothbrush. If parts are caked with minerals, soak them overnight in vinegar.

If cleaning or replacing the sprayer does not solve the problem, shut off the water. Remove the spout and find the diverter valve. On this model it is in the faucet body. Pry out the valve with a knife.

There are just too many small parts involved in this. I personally feel replacing it may be a better option if the damage is high. The parts are too small and for a newbie into repairs this can be a tough one. www.luxurylivingdirect.com
